HD camcorder based on the HV20, the HV30 offers some physical body improvements as well as a new shooting mode "30p" or (30 fps, true progressive).
- Fujitsu MB8AA101, which includes
- FR71 32bit RISC processor
- Toshiba TMP19A64C1D (very likely), which includes
- Toshiba TX19A MIPS-derivative core, fully MIPS32 and MIPS16e compliant, with additional support for MIPS16e-TX extensions.
No other hardware info about the HV30 is known.
There's a white plug that is accessible through a utility panel hidden by the battery when the camera is assembled. The HF10/100 has it as well.

Things to do
Analyzing the differences in firmware between the HV20 and HV30 would be a very good start, since the interior hardware appears identical between the two camcorders, and the firmware versions should be identical apart from the new 30p mode.
